Your right a thermisitor is a varable resistor that changes with heat. Basically this is what i'm doing. I'm getting rid of the thermistor because I don't want the voltage to vary with heat I want it to stay at one voltage and stay there contantly. And I think your right about the resistor, I think it's working like a load device in my certain cituation where it's a low amperage circuit and putting a resistor basically just drops all voltage through it, obvoiously i need some sort of thing that will drop the voltage, but not create a load on the circuit. How does a transformer work, and how would i hook it up to two wires?
